INHALING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 631,575, dated August 22, 1899.

Application filed October 21, 1898. Serial No. 694,188. (No model.)

T0 at whom it may concern:

Be it known that I, VALENTIN KOCH, manufacturer, a citizen of the German Empire, residing at Geneva, Switzerland, have invented certain new and useful Improvements in Inhaling Apparatus, of which the following is a specification.

This invention relates to an inhaling apparatus which is so constructed as to be used either for inhaling hot filtrated air or the dry or wet vapors of any suitable medicinal product whatever, or both.

The apparatus may be made in any suitable size and of any desired material; and the invention consists of an inhaling apparatus comprising a boiling-chamber, means for heating the same, a heat-radiating tube extending through said chamber, an air-chamber surrounding said boiling-chamber, a compartment, tubes connecting said boilingchamber and air-chamberwith said compartment, a cooling-tube connected with said compartment, means for supporting a medicament in contact with the vapor entering said tube, and an inhaling-tube connected with said cooling-tube; and the invention consists, further, in certain details of construction and combinations of parts,which will be more fully described hereinafter and finally pointed out in the claim.

In the accompanying drawings, Figure 1 is intended to contain a supply of medicinal,

preparations to be used with the apparatus.

The said foot or base supports a cylindricalv casing B, having a laterally-extending portion or compartment 13 and provided in its main portion B with an alcohol-lamp O. The casing B is provided with openings b and supports the boiler B which is traversed by the heat-radiating tube B which also serves When the cover I) is placed in position over the up per end of the tube E the lam p-fiame is thereby extinguished.

The boiler 13 is provided with a double wall, whereby an air-chamber b is formed between the inner wall 19 which contains the Water to be vaporized, and the outer wall of the boiler. chamber 19 is provided with a safety-valve 19 The air-chamber b of the boiler B is connected by means of a tube K to an air-filter K, in which a suitable sterilizing material It is contained. In the drawings the said tube K and filter K are placed in line with the tube L, so as to render the operation of the apparatus clear; but in reality the said tube K and filter K are placed at another point of the wall of the boiler, so that the air entering the air-filter K is caused to circulate within the air-chamber 19 before escaping into the said tube L.

The tube L connects the air-chamber with the compartment B into which enters the end of a steam-tube M parallel to the air-tube L. The said tube M is connected to the boiler by a coupling B and is provided with a cock M b indicates a discharge-pipe which is provided with a suitable blow-oft cock. (Not shown in the drawings.)

The compartment B is provided with a receptacle S for condensed steam. This receptacle is provided with several openings 8, over which a screen 8 is arranged, the purpose of which is to control the openings 3. The latter permit the escape of any uncondensed steam which may enter the receptacle and remain uncondensed therein.

Upon the compartment B is supported a vertical cooling-tube O, in the lower part of which is arranged a medicine-tube N. The

said tube N is provided with a tapering concentrical inner tube at and with a cover N having suitable openings n The medicine is placed between the tubes N and n, and the steam entering the latter as shown by the arrows is thrown back by the cover N inpon the said medicine and escapes then through the openings n into the tube 0, from which it passes through the valve-top P and inhalingtube Q and mouthpiece B into the mouth of 100 The inner portion or boiling-- the patient. The vertical cooling-tube 0 contains a series of superposed conical partitions 0 o 0 0 provided with suitable holes,through which the steam passing in the tube 0 takes its way in the manner shown by the arrows in the drawings and is cooled thereby. The conical partitions o o o 0 are connected with one another and with the valve-cap P of the tube 0 by means of a rod 0, so that when it is desired to clean the tube 0 the top piece P is removed, thereby withdrawing the partitions, so that the tube may be easily and thoroughly cleaned.

The cap P comprises a valve box or casing, in which a return-valve p and a blow-valve p are arranged. The valve 1) is formed of a star-shaped plate, which is free to move up and down and is guided by its points on the wall of the cap. The valve 12 is formed of a disk, which is also free to move up and down. Above the said valve 1) there are provided several openings p in the cap P. The cover P of the cap P is removable.

The tube P of the valve-cap P serves for attaching a flexible tube Q, to the outer end of which the mouthpiece R is aflixed. The tube Q is preferably provided with a waterpot q, extending at an angle from an intermediate tube Q, inserted, preferably, in the middle of the length of the inhaling-tube Q, as shown in Fig. l.

The operation of my improved inhaling apparatus is as follows: \Vhen steam is generated in the boiling-chamberN, if the cock M is open the steam enters the casin g B through the tube M and passes thence through the apparatus, causing a suction to be produced in the tube L. Atmospheric air is thereby drawn in through the filter K, circulates in the air-chamber Z), enters the tube L, and passes, with the said steam, in contact with the medicine contained in the medicine-tube N. The thus impregnated vapor passes through the conical partitions 0 and the valve 1') and the tube Q and is delivered from the mouthpiece R to the patient.

A modified form of medicine-tube is shown in Fig. 4:. In this construction the tube N is closed at its bottom portion and no steam passes through the same. The steam arriving in the compartment B of the apparatus, as described above, serves only to heat the said tube N and causes the medicine contained in the same to be evaporated. The medicinal vapor thereby formed in the tube N mixes with air which enters through a series of holes 07, at the top portion of the tube N which is located outside of the compartment B and the mixture then passes out through the tube 0, the mouth of which is below the openings n and opposite the mouth of the medicine-tube, and thence into the in haling-tube Q and mouthpiece R. The steam in the compartment B passes out of the same at b through the blow-off cock before mentioned, which is opened for the purpose.

Having thus described my invention, I claim as new and desire to secure by Letters Patent An inhaling apparatus, consisting of a boiling-chamber, means for heating the same, a heat-radiating tube extending through said chamber, an air-chamber surrounding said boiling-chamber, a compartment, tubes connecting said boiling-chamber and air-chamber with said compartment, a cooling-tube connected with said compartment, means for supporting a medicament in contact with the vapor entering said tube, and an inhalingtube connected with said cooling-tube, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.

VALENTIN KOCH.
